Alexander and Sadiku utilize phasor notation to define $\mathbfS$, which encapsulates all power information: $$\mathbfS = \frac12 \mathbfV \mathbfI^* \quad \text(using peak values)$$ $$\mathbfS = \mathbfV rms \mathbfI rms^* \quad \text(using RMS values)$$ Complex power is measured in Volt-Amperes (VA) and is comprised of two components:
While your query mentions "11," please note that the book is currently in its as of recent years; "11" typically refers to Chapter 11 , which focuses on AC Power Analysis , a critical topic in alternating current systems.

La ricerca della dicitura fa spesso riferimento alla ricerca dell'undicesimo capitolo di questa monumentale opera (dedicato all'analisi della potenza in regime sinusoidale della sesta o settima edizione italiana) oppure alla ricerca di specifiche versioni digitali del testo.
by Charles K. Alexander and Matthew N. O. Sadiku (often localized in Italy as Circuiti Elettrici or Fondamenti di circuiti elettrici ) is arguably the most famous textbook used by engineering students worldwide to master electrical engineering. Nel dominio dei fasori la relazione diventa: V=jωLIbold
Ecco i punti chiave riguardanti la disponibilità e i contenuti del testo:
(released around 2020)—the core content remains consistent across recent editions. The textbook is globally recognized for its six-step problem-solving methodology

Before diving into the Italian version, it is essential to understand the greatness of the original. First published by McGraw-Hill, Fundamentals of Electric Circuits is designed to present circuit analysis in a clearer, more interesting, and easier-to-understand manner than more traditional texts. It is known worldwide for its balanced and systematic approach, which perfectly combines theory with an immense number of practical examples.
